    Abstract:
    INTRODUCTION: Guillain-Barré syndrome (GBS) is an immune-mediated disorder of the peripheral nervous system. Respiratory failure requiring mechanical ventilation (MV) is a serious complication of GBS. Identification of modifiable risk factors for MV and poor short-term prognosis in mechanically ventilated patients with GBS may contribute to the individualized management and may help improve the outcome of the patients. METHODS: We retrospectively analyzed the clinical data of 541 patients who were diagnosed with GBS from 2003 to 2014. Independent predictors for MV and short-term prognosis in mechanically ventilated patients were identified via multivariate logistic regression analysis. RESULTS: The mean age was 41.6 years with a male predilection (61.2%). Eighty patients (14.8%) required MV. Multivariate analysis revealed that shorter interval from onset to admission (p < 0.05), facial nerve palsy (p < 0.01), glossopharyngeal and vagal nerve deficits (p < 0.01) and lower Medical Research Council (MRC) sum score at nadir (p < 0.01) were risk factors for MV; disease occurrence in summer (p < 0.01) was a protective factor. As to prognostic factors, absence of antecedent infections (p < 0.01) and lower MRC sum score at nadir (p < 0.01) were predictors of poor short-term prognosis in mechanically ventilated patients regardless of treatment modality. We further investigated the predictors of poor short-term prognosis in patients requiring MV with different nadir MRC sum scores. Combined use of intravenous corticosteroids with intravenous immunoglobulin (odds ratio 10.200, 95% confidence interval 1.068-97.407, p < 0.05) was an independent predictor of poor short-term prognosis in mechanically ventilated patients with a nadir MRC sum score from 0 to 12 points, regardless of existence of antecedent infection. CONCLUSIONS: Clinical predictors of MV and poor short-term prognosis in mechanically ventilated GBS patients were distinct. Add-on use of intravenous corticosteroids was a risk factor for poor short-term prognosis in mechanically ventilated patients with a nadir MRC sum score from 0 to 12 points.
